    摘要： Disclosed is a method and a system for developing a photo-resist material of an optical recording medium on which digital information is recorded in the form of a series of pits whose position and length represent the digital information. In order to precisely control the size of the pits formed during the developing process, and to reduce the deviation from one recording medium to another, a monitoring beam is applied on the recording medium during the developing process. A diffraction beam of the monitoring energy beam passes through the pits, and is received by a sensor means which monitors the intensity of the diffraction beam and which produces a signal for controlling the supply of developing solution on the recording medium.

    摘要： Disclosed herein is an optical disk comprising an elastomer layer formed on a transparent substrate and having infinitesimal bumps and depressions such as pre-addresses or pre-grooves, and a reflection retention layer which is formed on the elastomer layer and which comprises a thiophene vinylene resin having a glass transition temperature and, after curing, a high reflection factor. The reflection retention layer having high levels of affinity with polymers minimizes the possibility of its delamination from the elastomer layer. This makes it easier to form the reflection retention layer.

    摘要： An optical disk manufacturing method comprises a step of preparing a master disk having an elastomer layer, formed on a transparent substrate and containing photosensitive dyes, and a polymer support layer, formed on the elastomer layer and having a glass transition temperature; a step of forming minute bumps on the master disk by irradiation of a focusing laser beam; a step of forming a metal layer on that surface of the master disk which has the minute bumps; and a step of forming a stamper layer on that surface of the master disk which is rendered conductive, thereby forming a stamper. According to another optical disk manufacturing method, the metal stamper forming step is replaced with a step of forming a transfer layer, made of a transparent ultraviolet-ray hardening resin, on that surface of the master disk which has the minute bumps, thereby forming a resin stamper.
